Title
(EN) METAL-CORED ELECTRODE FOR PRODUCING LOWER SLAG VOLUME WELDS
(FR) ÉLECTRODE À NOYAU MÉTALLIQUE POUR PRODUIRE DES SOUDURES DE VOLUME DE LAITIER INFÉRIEUR
Abstract
(EN)
Utilizing a hydrogen compound source as an arc stabilizer is counter intuitive to standard formulation design practices which often strive to limit or eliminate hydrogen from the welding arc and weld pool. The present disclosure is directed to a tubular metal-cored welding electrode that comprises a metallic sheath disposed around a granular metal core in which the granular metal core comprises an alginate arc stabilizer (as a hydrogen compound source) configured to release hydrogen near a surface of a workpiece during welding. The tubular metal-cored welding electrode may further comprise primary de-oxidizers such as manganese and silicon. In certain embodiments, the amount of manganese in the tubular metal-cored welding electrode may be minimized or eliminated. The tubular metal-cored welding electrode may also comprise nickel or titanium.

L'utilisation d'une source de composé hydrogéné en tant que stabilisateur d'arc est contre-intuitive par rapport aux pratiques de conception de formulation standards qui s'efforcent souvent de limiter ou d'éliminer l'hydrogène de l'arc de soudage et du bain de fusion. La présente invention concerne une électrode de soudage à noyau métallique tubulaire qui comprend une gaine métallique disposée autour d'un noyau métallique granulaire dans laquelle le noyau métallique granulaire comprend un stabilisateur d'arc à base d'alginate (en guise de source de composé hydrogéné) conçu pour libérer de l'hydrogène à proximité d'une surface d'une pièce à travailler pendant le soudage. L'électrode de soudage à noyau métallique tubulaire peut en outre comprendre des désoxydants primaires tels que le manganèse et le silicium. Dans certains modes de réalisation, la quantité de manganèse dans l'électrode de soudage à noyau métallique tubulaire peut être minimisée ou éliminée. L'électrode de soudage à noyau métallique tubulaire peut également comprendre du nickel ou du titane.
